Auto Collision Experts

I brought my car in for an estimate and made an appointment for my car four weeks in advance, even though they were only one week out, as I had another car available to me over that time. They were to take care of a dent in the fender and fix four small dings from the last hail storm. I brought the car in as scheduled, they said they would have it back to me before I had to return the car I was using (four days). Two days later, they called me to tell me they could not work on my car because their hail damage guy no longer worked there. Even though I could not understand why it took them two days to figure that out, I asked them to fix the fender, as that was the main issue, but they just said no, they were too busy and I would need to schedule another appointment to bring it in. I explained I had been first on the schedule based on how early I scheduled and that I just need to get it fixed, but they refused. I went in to pick up my car and talked to the manager, but he said they were just too busy to work on my car. I pointed out I should have been first on the schedule, but he just said I can re-schedule but they can't work on it now.
So, I have no idea if the work they do is good or not, as they seem to be reluctant to actually perform any work.
